TION, A. CORPORATION OF DELAWARE APPARATUS FOR SEPARATING LIQUIDS FROM SATURATED FLUIDS AppIication filed August 28, 1926., Serial No. 132,283.

This invention relates to an apparatus'for separating the gasiform content and the liquid content of a saturated fluid. V The gasiform content and the liquid content maybe derived from the same substance rator.

as steam from water, or may be derived from diflerent substances as in separating water vapor from gas in a water gas, etc.

-The object of the invention is to provide a device by which the gasiform content and liquid content of a saturated fluid may be quickly and efficiently separated.

The apparatus shown is designed for use in separating fluids which pass through the device under pressure. The invention espe cially is usefulin connection with a steam valve, in whichconnectionit is desired to separate the liquid content from the gasiform content of saturated steam, and thereby enable the water or liquid content to be returned to the boiler and the gasiform content substantially denuded of moisture, topassto the 7 engine or other point of work. Theinvention is also well adapted for use i i inthe manufacture ofwater gas, where itis desired to pass the gas to the main in a comparatively pure state, and substantially free from moisture and condensates, thus prevent-.

ing the moisture and condensatesfrom reaching the main, and ultimately the gas meters,

I where the effect uponthe diaphragms of me- 1 ters, of-the dry type is deleterious.

A-further object of the invention is to prol vide a separator through which the'liquidladened fluid isjpassed under pressure and divided into attenuated streams, and caused toforcefully impinge against a perforated surface, through which the gasiform content a ofthe substance passes, substantially denuded of moisture, the liquidor condensates being trapped and directed back to the source of thesaturated fluid. In-the drawing illustrating V Figure 1 is a sectional view of the separator, or apparatus. f y .Figure2 is an elevation'of the cage and parts carried thereby removed from the sepa- Figure'3 is a sectional view of a 'portionof the invention,

a steam valve of the marine. type, showing.

. is in. operation.

I Referring to the. drawing: 7

The numeral 1 designates a casing provided at its bottom with an annular flange 2, by

which it maybe bolted to a boileror other' sourceeof the fluid desired to be separated.

Theicasing isprovided with another flange 3, by Wl'llCll the casing 1 may be bolted to a pipe or main, leading-to an engine or other object to which it is desired to deliver substantially 1 liquid-free gasiform fluid.

V The casing is provided wit-ban inlet open- 111g 4, and'an outlet opening5. Stationaril y held within the casing is a cylinder 6, preferably closed at its top as indicated at 7. This cylinder is provided circumferentially with numerous outwardly flowing perforations or nozzles 8. 5

- Stationarily'positioned within the cylinder 6 is a cage 9, provided circumferentially and preferablythroughout its entire circumference with vanes or slats 10, suitably spaced apart, thus providing numerous narrow'slots .11. The cage is closed at its top by a cover 12, but its. bottom is open so as'to permit, say .for instance steam, to pass through the slots and thereby be divided into numerous attenuated streams and bev caused to forcefully impinge against the inner periphery ofthe cylinder. The cage below the slots is provided with a fiange 13,extending virtually entirely around the cage with the exception of a portion presently mentioned.

This flange extends beyond the periphery of the cage, with its outer edge fittingsnugly against the innerwall of'the cylinder, as

ment to the boiler and to the pipe leading ting 19, intowhosevertical branch is threaded a drain pipe 21. g r y In Figure 3 the separator is shown applied to a steam valveof the marine type,

such as is shown and described in my pending application, Serial No. 68,719, filed-No vember 12, 1925 now Patent Number 1,7 A,331, January 21, 1930. Referring particularly to this figure the numeral 1 designates a valve casin havin an inlet openin 22 and'an or a: l an outlet opening 23, the valve body adjacent to the openings, being flanged for attachto the point of work, as usual.

The numeral 24 designates a stop valve, which seats upon a seat 25 on seat ring 26, threaded into the valve body. The stop valve is providedwith a cylindrical extention 27, provided circum'ferentially for "a considerable portion of its length with numerous perforations or nozzles 28; Secured to the extension 2'7, and within the same, the separator is secured. In attaching the separator to a valve, I preferably provide the cylinder 27 with a bracket 29, and a central boss 30, through which the drain pipe 21 is guided in the opening and closing movement of the valve. 7

In any application of the separator it will be understoodthat the drain pipe 21 returns to the source of the liquid laden fluid, from which source, as before intimated, the fluid passes through the separator under pressure.

The numeral 31 designates the valvestem, through which,'1t will be understood, the valve is opened-and closed.

into the inlet 4, through the open bottom of the cylinder 9, and throughthe slots between the "anes or slats of the cage and forcefully impinges according to the pressure under' which it enters the inlet opening against'the inner periphery of the cylinder against which the water, in the case of steam, is separated from the steam, and the condensate forms on the inner periphery of the cylinder, while the steam virtually or substantially denuded of its moisture, passes through the perforations or nozzles to the point of work. The moisture accumulating on the inner surface of the cylinder falls down upon the flange 13 and flows to the sumps 17, from which it passes through the pipes 18, to the drain pipe 21, and thence back to its source.

By placlng the mlet and outlet openings 1n 7 angular relationship, the direction of the flow of the steam is abruptlyinterrupted which greatly facilitates the separation of the water from the steam. In the present arrangement wherein the inlet t is vertical and the outlet 5 horizontal, which arrangement under some conditions may be reversed, the steam passing between the vanes of the cage or turbine 9 is carried in a horizontal direction against the perforated wall of the sleeve or cylinder 6 and said sleeve being surrounded by steam will balance the particles of water separated from the steam and permit them to drop by gravity within the space between the cage and sleeve and reach the sump, the particles of water at this time being balanced, thus avoiding the possibility of being carried on again by the steam flow, which would hap pen if the outlet was in line with the inlet.

Claims:

1. In a separator of the character described, the' combination of a hollow body having an inlet opening and an outlet opening, a second body within the first mentioned one and interposed between said inlet and outlet openings, said second body provided with numerous small perforations, a cage within the perforated member and provided with a flange ofgreater diameter than the cage, whereby said cage is spaced from the inner periphery of the inner body, to form an annular channel between the inner body and lower portion of the cage to entrap the condensates of the fluid passing through the body, and means communicating with said channel whereby the entrapped condensates are disposed of.

' 2. In a separator of the character described, in combination, a hollow body having an inlet opening and an outlet opening, a second hollow cylindrical body within the first 'mentioned body and provided with numerous small perforations or nozzles, a cage within the second body and provided at one end with a flange of greater diameter than the cage, whereby said cage is spaced In operation the fluid to be separated passes from the inner periphery of the inner wall of the second body, said flange together with the cage and inner wall of the second body forming an annular channel between the cage and said body to trap the condensates, said channel being provided with sumps, a bleeder pipe entering said sumps wherethrough the condensates entering the sumps are disposed 3. A separator as claimed in claim2, characterized in that the sumps are oppositely disposed in the cage flange, and that the bleeder pipe opens into each of said sumps, and that the openings in said pipe lead to a common outlet. r

4. In a separator of the character described, the combination of a hollow body having an inlet opening and an outlet opening, a second body within the first mentioned one and interposed between the inlet 'and'outlet openings, said sec'ondbody being provided having angularly disposed openings therein,
